comma AND GREASING PRESS;

Application filed September 2, 71926." Serial No. 133,2ii.

, a Myinvention relatesto presses for cut-ting and creasing sheets ofpaper, cardboard or other stock and the invention may be applied to aprinting press which is'used for cutting and creasing or to a pressspecially built for cutting andcreasing. he invention is shown hereinapplied to aflatbed press though it will be apparent thatmy invention isnot limited to this'application. W

on. a bed 'and cylindercutting and creasing press the sheets are cut bymeans of a form or dieplaced on the bed. sheet of cardboard is fed tothe cylinder and as it passes between the bed and cylinder it is cutinto-suitable sections to make boxes and it is creased on the lines onwhich bends or folds are to be'made. It is customary to leave ties" ortabs connecting various portions of the sheets conne'cted' where theywould be otherwise entirely severed by the cutting rules, in

order that sections of the sheet will be temporarily held together untilthe sheet is delivered from the press, the sheets being stripped afterthey are deliyered from the prcsstofrernove Or -break these-tabs'orties. It

often happens that these tabs or ties arenot strongenough to preventportions of the cut andcreased sheets from separating and the tabs orties w ll sometimes fall upon the die or form and the" present inventionis adapted to removethe same from the die or form if they fall thereon.The present device embodies a member such as a brush for removing suchparts from the die or form and in the full embodiment of the inventionthe'brush is adapted to be operated so that it wipes the form or dieeither on the forward or back wardstroke, or both, as may be required bythe particular kindbf job in hand. In additionI providemeans for,catching and holdsuch material as the brush may sweep fromtheform ordie, in order that the same will not scatter upon other portions of thepress or its'fn' echanisms andso that the re moved material may beconveniently taken this apcarries the sheet around with it.

there, thus sweeping the none of a press as may be necessaiy'toillustrate the application of my invention. Herein I have shown one ofthe side frames of the press, the feed table 2, from which the sheetsare fed, the impression cylinder 1, the sheet delivering device 7 fordelivering the sheets from the cylinder, and the reciprocatlng bed3,1nwing a form or die 4 of cuttingand creasing rules. In Figure 1 theimpression cylinder is shown in position to take a sheet from the feedtable 2, and as the cylin der revolves in the direction of" the arrow,it At this time the bed 23 is moving toward the cylinder (in thedirection of its arrow) and as the bed runs under the cylinder the dieat cuts and creases the sheet on the cylinder. The

sheet now passes on up" with the cylinder at 5 and dur ng this time cutportions are likely to fall out on the die, or if they do not fallentirely out'they' may come partly out, and these hanging portionsare'likely to hold. onto some part'ofithe die.

A brush 26' extendsentirely across thie press, over the path of the die:and it is attached to arms 27 ((ine at each side of the press);These-arms are fixed on the shaft 28 and this shaft is capable of beingrocked slightly by means of a lever-'29, stud and v This cam 32 can beattached to any shaft which makes one revolution per complete'cycle ofthe press.

I have shown it attached to thecross shaft with the bed moving in eitherdirection, or

bythe simple expedient of slipping the cam endwise on the shaft thelever 29 can be made to come down against the stop l0 and remain dieduring both strokes of the bed. r

At 345 and "I have shown trays attached to opposite ends of the bed tocollect. the sweepings from the operations of the brush. In Figures 3and d I have shown a fixed brush which will always sweep in bothdirections of movement of the bed. Here the brush is designated 36 andit is attached to a bar 38 extendingjacross the press and liXed' brushmay be arranged to sweep the die in gitllel direction of'iiioveineiit ofthe bed "orit may be set to sweep the die in both directions of movementof the bed. As forei n material cuttings were allowed to remain. tingsor foreign material, even if they should no is swept from the die by thebrush it is deposited in the tray at one end of the bed or when thebrush'is sweeping the diein both directions the foreigniiiatter maybe'swept into both trays alternately as the bed moves back and forth.From thesetrays the refuse may be cleared out when the press isstopped.

YVith this arrangement the foreign substances are collected instead ofbeing allowed to scatter through the press and clog the workingmechanisms. The die can be kept clean at alitimes and this will protectthe die from injury which might otherwise occur if the These cut notcause injury to the die would, if allowed to remain on the the, affectthe operation of the rules of the die on sheets which are fed throughthe press, resulting in defective and'ci easing stock including acutting die,
